CSS, or Cascading Style Sheets, is an essential part of modern website design and developing. CSS is what helps web developers to define the look and feel of web pages. In simple words, CSS coding and CSS programming is used to add style to web pages and make web pages and websites pretty, beautiful, unique. CSS defines how HTML elements are to be displayed.
What is CSS
CSS (Cascading Style Sheets) is designed to enable the separation of document content written in HTML from document presentation (layout, colors, fonts). CSS coding is also used to style XHTML and XML markup.
Styles are stored in external .css files enabling you to make changes to the website layout by editing just one single file. This style sheet acts like a switchboard, communicating with the various pages on a website and telling them how and what to display.

Why use CSS
CSS specifications are maintained by the World Wide Web Consortium (W3C). The W3C developed CSS coding to help web designers and web developers to add fonts, colors and other formatting to web pages. All formatting can be stored in a separate CSS file. Developed in 1997, CSS helps web developers to separate content from design and save a lot of their design and development time and work. Today, all modern browsers support CSS Levels.
Prior to CSS, the presentational elements of HTML docs were contained within the HTML markup. All background styles, borders, fonts, etc had to be repeatedly described within the HTML file. Cascading Style Sheets allow web developers create a simpler HTML and move much of the formatting information to separate file.
There are Author Style Sheets (created by the web page author); User Style Sheets (set by the web page user); User Agent Style Sheets (styles applied by the web browser to display the web page).
Why learn CSS
Cascading Style Sheets is a very powerful skill web designers and web developers use to build professional website. Although there is so much to learn about CSS, using CSS programming is a must in modern website developing. CSS gives lots of great options and allows enhancing the website in both look and functioning. Web designers use CSS for their design and development, so it is important to understand and learn the basics of HTML and CSS.
